Abstract
Dear Editor,
We are grateful for the interest in our short report [[1]] and pleased to hear that the report has added a useful contribution to research in this field. Thank you for these comments and the points raised. We have been transparent in our report that this study was conducted within available time and resources and the sample size and number of devices reflects this approach. We are aware there are differing views regarding analyses and, with such fast moving technology, an ever increasing and changing variety of tools to measure step count and physical activity. This provides opportunity for future research exploring the validity and reliability for a plethora of tools and devices. The message our study highlights is that not all measures of step count that patients use provide reliable information regarding their step count and that the reliability of App pedometers cannot be assumed when used in research. The interesting and relevant comments raised in this letter do not detract from this conclusion and helpfully raise suggestions for future research. We look forward with interest to see the findings of future studies exploring this under-researched topic in greater depth.
